专利汇可以提供Silver halide photographic sensitive material专利检索,专利查询,专利分析的服务。并且PURPOSE:To attain high sensitivity and low fog by forming an emulsion layer contg. silver gromide and/or silver iodoromide-base silver halide particles of a specified form and an unstable selenium compound. CONSTITUTION:Silver bromide and/or silver iodobromide-base silver halide particles contg. silver chloride are prepd. so that each of the particles has a crystal face having a ridge at the center of (110) face and/or (110) face. The silver halide particles are core-shell type ones having higher silver iodide content in the cores than the shells. The silber halide particles are sensitized with selenium by adding an unstable slenium compound such as N,N-dimethylselenourea. Since the emulsion layer formed contains the specified silver halide particles, low fog and satisfactory shelf stability can be attained while selenium sensitization is carried out.,下面是Silver halide photographic sensitive material专利的具体信息内容。
